Basic Cofiring Characteristics Of Ammonia With Pulverized

Basic Cofiring Characteristics Of Ammonia With Pulverized

Dec 14, 2018nbsp018332In this study, basic co-firing characteristics of pulverized coal and ammonia were investigated using a bench-scale single burner test furnace. A schematic diagram of the single burner test furnace is shown in Fig. 1. The rated thermal input of the furnace is 760 kW, which corresponds to approximately 100 kgh of coal for common bituminous coals.
